I bought the K7XX and TH-X00 (mahogany) on their first drops and both were just fine. there was an issue with bubble wrap imprints on the TH-X00 purplehearts (which I did not purchase). The pictures of these marks looked pretty faint, but it made for some unhappy customers.
There are several "tiers" of labour quality in China and elsewhere, so that isn't definitive. As for the "second one" - I meant the next time these drop (I'm sure this won't be a one off) - I want to read some impressions first, moreover I jumped in the current K7XX drop.
